To all whom it may concern:

Be it known that I, MIGUEL Baaaros Gomnz, a citizen of the Republic of Mexico, and a resident of Mexico city, Mexico, have invented a certain new and useful Imgnovement in VehiclePTires, of which the ollowin is a specification.

' This invention relates to vehicles tires, and more particularly, to a substitution of the inflatable inner tubes and of the solid Various attempts have been made to provide a solid vehicle tire which possesses the characteristics of. resiliency, strength, simplicity, cheapness, lightness and durability, necessary for general use and for taking the place of the pneumatic tires. These attempts have, however, been unsuccessful, exceptmg for heavy, freight-carrying vehicles, in which the resiliency of the tires is a secondary consideration. In vehicle tires as now constructed, with an inflatable inner tube, there exists always the danger that objects will penetrate t e casing and puncture the inner tube, causing the high pressure to blow ahole in the tube, and frequently rip open the casing. Moreover, rim-cutting of the casing, pinching of the inner tube, flat tires and other accidents will shorten considerably the life of pneu-' matic tires, besides occasioning heavy .expenses for repairs. I

Some of the objects of this invention are to provide a tire m which the inflatable inner tube will be substituted by a layer or filler of triturated, agglutinated cork, in such a manner as not to impair the necessary resilency of the tire. Further objects will appear from the detailed description taken in connection with the accompanying drawing, in which:

Figure 1 is a side elevation of the tire constructed according to my invention.

Fig. 2 is a longitudinal section through a section of a tire embodying this invention, showing the position of the cork filling,

Fig. 3 is a cross section through'the same tire.

In accordance with this invention, the tire is constructed of an elastic material, such as rubber, which has combined therewith a. la er or filler of triturated, agglutinated cork around the center of the tire, filling the which extends circumferentially :apace occupied in pneumatic time by the inatable inner tube. In order to increase the necessary cohesion of the cork, I prov1de layers of reinforcing material, such as tlre fabric, which extend transversely around the cork filling; however, these layers are not absolutel necessary, as the body of triturated, agg utinated cork will form, after vulcanization, an integral structure with the outer rubber bod Referring to the accompanying drawing, 1 designates the cork fillin surrounded by the layers of fabric 3, an inclosed by the rubber body 4. The wheel and rim may be of any suitable construction.

The tire 4 is formed of a body material of rubber, or of a suitable material havin the characteristics of rubber, and the we. thickness is atest on the traveling surface or tread of t e tire. In accordance with this invention, the center of the tire is formed by a body of triturated, agglutinated cork, which mayA be mixed, impregnated or imbibed wit rubber, natural or artificial caoutchouc, bichromated gelatin, elastic collodion, casein, or with any other analogous substance whlch will impre ate the cork and form with the same an integral coherent structure.

This filling material is surrounded by re inforcing layers ofasuitable fabric and the outer rubber bod applied successively, and the whole may e vulcanized together or the cork filling and the layers of f ric may be vulcanized separately and the rubber bod applied and vulcanized successively. en formed and vulcanized the cork, the reinforcement and the rubber body will form an integral, coherent structure.

In order to increase the resiliency of the tire and to prevent any deformation of the cork filling through the heavy pressure on the tire, I provide, on each side of the agglutinated cork body, a cushion 2 of rubber or of any other elastic material, the convex face of said cushions bei adjacent to the slightly concave sides 0 the cork body. These cushions extend the whole len h of the filling and are inclosed by the reinforcing material, forming an integral structure with the same after vulcanization.

It is obvious that various changes m y be made in the details of construction without departing from the spirit of this inven- Patented Feb. 11, 1919.

tion, and it is, therefore, to be understood that this invention is not to be limited to the specific details shown and described.

What I claim is:

1. A tire including a hollow rubber body, a core having concave sides, layers of fabric envelopin such core and rubber cushions interposed between such fabric and the sides of the core.

2. A tire including a hollow rubber body, a core having concave sides, lagers of fabric enveloping such core, and ru ber cushions sides fitting mm the concave sides of the core.
